He's around 1 - 2 months old, plenty old enough to be running and playing like a normal kitten. He's veryyy wobbly when he walks and it seems as if he keeps stretching his legs while walking.. like.. excessively. I stretched/bent his hind legs and checked his hips and nothing seemed to hurt him. I also checked his feet and nothing hurt when i bent toes and nothing was in his feet. If he's doing this and doesn't seem to be in pain I suppose hes fine but I would love to know any information on why he would be doing this.. He showed up at my house randomly so I'm not positive on his age, but it's very likely. He's a somewhat mature kitten so he shouldn't have anymore trouble walking. Help?
